Permatex Ceramic Extreme Brake Parts Lubricant — 8 oz Purple Tube, High-Temp & Water-Resistant

Permatex 24125 Ceramic Extreme Brake Parts Lubricant is a 100% synthetic, ceramic-infused grease designed to silence brakes and protect critical brake components across extreme temperatures.

This ceramic-based brake parts lubricant combines synthetic carrier oils and real ceramic solids to deliver long-lasting lubrication and noise reduction where ordinary greases fail. Formulated to resist moisture, corrosion and contaminants, the product stays in place rather than washing away, and it remains effective over a very wide operating range. The purple, non-melting formula is intended for use on disc brake caliper hardware, pistons, sleeves, and other mating surfaces where heat, friction and environmental exposure challenge performance.

How does this lubricant reduce brake noise and vibration?

The ceramic solids in the formula create a stable, dry film that dampens squeal and chatter by reducing metal-to-metal and metal-to-rubber friction. Its resistance to breakdown at high temperatures preserves the damping layer when braking heats components repeatedly. Use in combination with correct pad installation for best results.

• Ceramic particles form a thin, noise-dampening barrier
• Maintains consistency up to very high temperatures
• Reduces metal-on-metal contact on caliper hardware and pistons

Will it hold up under harsh temperatures and wet conditions?

This lubricant is engineered for extreme thermal tolerance and water resistance so it remains effective from very cold starts through intense, repeated stops. The synthetic base resists washout and resists contamination, so the protective layer endures in wet, salty or dusty environments. It’s intended to maintain lubrication across the life of pad assemblies.

• Operates over a very broad temperature window without melting
• Resistant to moisture, corrosion and contaminants
• Designed not to wash out under wet conditions

Where should I apply this product on my brake system?

Apply sparingly to sliding surfaces and hardware where controlled lubrication prevents seizure and noise. Typical contact points include caliper guide pins, contact pads, pistons and rubber sleeve interfaces. Avoid applying to friction surfaces of the brake pads or rotor braking faces.

• Caliper guide pins and bushings
• Piston skirts and mating surfaces (external, as recommended)
• Rubber sleeves, seals and other compatible plastic hardware

Is it compatible with rubber and plastic brake components?

Yes — the formula is compatible with many internal and external brake rubbers and plastics, including ethylene-propylene rubber. It’s formulated to avoid swelling or degrading typical brake hardware materials when used as directed. Always check component manufacturers’ recommendations if in doubt.

• Safe for ethylene-propylene rubber and commonly used brake plastics
• Non-reactive with many OEM hardware materials when applied correctly
• Helps prevent sleeve and bolt seizing and galling

Who is this for: Technicians, DIY mechanics and workshop professionals who need a high-temperature, long-life lubricant for disc brake hardware will find this Permatex product useful. It suits anyone servicing calipers or replacing pads who wants reliable corrosion resistance and sustained noise control without frequent reapplication. Do not use on friction surfaces where braking material contact is required; follow vehicle service guidelines for safe application.
